y Application filed January This invention relates to an improvement in oil stoves or the like and has for its object Ythe provision of a stove wherein heat is efliciently generated with economy in the consumption of fuel and safety in the operationof the burner and in which the heatfrom one burner may be advantageously utilized to simultaneously heat a number of lids and consequently a number of cooking utensils or the like to secure the full heating effect of the burner and to prevent waste of the heated products of combustion.

Another object resides in the lprovision of a burner having the advantages and capaci- Vties enumerated and which is susceptible of convenient and graduated control and also of simple and durable construction, reliable and safe in use and easy and comparatively inexpensive of manufacture.

@their objects and advantages reside in certain novel features of the construction and arrangement of parts which will be hereinafter more fully described and particularly pointed out in the appended claims, reference being had to accompanying drawings forming a part of this specification and in which: l

Figure 1 is a perspective view showing` one the invention;

'Figure 8 is a view in section on line 8-8 of Figure 27 and Figure9, is a detail view pipe. Referring to the drawings, the numeral 1 of the oil inlet designates generally an oil stove which has W9 and 10 are supported on ,ra lower shelf 2 supported on legs 3, sides 4, a top 5 and a back 6. Uf course the structure of the stove thus far described may be varied.- A plurality of lids designated at 7, 8,

the top of the stove7 the Vlids being fitted in openings proholder 20, 1925. Serial N0.' 3,659.

vided for the saine in the top and having ribs 11 which engage the top around the openings to support the lids in position. The lids are of substantially annular form and each has an inwardly inclined or bevelled top wall 12 adapted to support cooking utensils of various sizes in such manner that the base of the cooking utensil'closes the opening; defined by the annular lid in the top of the same.

Means is provided fory supplying lheat to the lid 10 and this means includes a burner having a cup member 13 supported at the upper end of an oil inlet pipe 14. rlhe upper end of the oil inlet pipe 14 is threadedly connected with the base of the cup member 13 atits center and projects above the bot tom of the base so that dirt and sediment will be deposited on the bottom of the base and will not fall back into the oil inlet pipe. The pipe 14 is filled up with wires so as to restrict necessary to supply the requirements of the burner. In lieu of the wires a rod which is smaller than the bore of the pipe may be fitted in the pipe. rllhe interstices between the wires or the interstice between the rod and the pipe provide the passageway for the oil.v This feature is one of safety and prevents conflagration or explosion. A plug l5 is set in the cup member 13 and has an opening 16 centrally of its base to receive the upper end of the oil vinlet pipe 14. Slots 17 are also provided in the base of the plug and extend from the opening 16 to the periphery of the plug. The plug 15 is somewhat smaller than the cup member 13 to provide a wich receiving space 18 in which a wick 19 is fitted. The upper' end of the plug 15 is reduced to provide a shoulder 19 Von which a combined wick holder and chimney support 2O rests. The combined wick and chimney support 20 comprises an inner' perforated sleeve 21 and an outer perforated sleeve 22 between which the wick 19 is fitted. The sleeve 22carries spider arm 23, the outer ends of which are connected to the lower section 24 of the chimney designated generally at 25 and made up of the section 24 and a section 26 connected with the lid 10. Between the sections 24 and 26 a sleeve 27 of asbestos Vis provided. As shown in Figure 5 the lower end of the section 24 is spaced from the cup member 13 to provide the air inlet around the burner and upper end of the chimney extends through the open bottom of the lid 10.

A casing designated generally at 30 1ncioses the burner and chimney and may consist of sheet metal sections 31 and 32 between which a layer 33 of asbestos is disposed. The asbestos is extended over the upper edges of the sections 31 and 32 and engages the under side of the top 5 of the stove. rlfhe section 31 is adjustably supyported as at 34 on the shelf A2 of the stove and the section 32 is carried on the section 31. A hinged door 35 is incorporated in the section 31. By adjusting the section 31 the top of the casing may be pressed firmly against the underside of the top 5 and prevent the escape of the warm air or gases. thereby enhancing the efhciency of the stove to a very material extent.

The oil is supplied through the inlet pipe 14 through a supply line 40 from a tank 41 in which a safety oil `feed connection 42 forming the subject matter of my co-pending` application Serial Number 202,937 is embodied. In this supply line Aa control valve 43 is also embodied and has an angu-v lar finger 44 fixed tothe axis of the hand wheel 45 by which the valve is adjusted. This linger 44 coaets with a bracket 4G having a curved portion 47 bearing numbers 4S so that the adjustments rof the valve may be made with precision. A stop lug` 49 is r integrally formed with the bracket 46 and limits the turning movement of the valve to such position as to supply the minimum amount of oil necessary to keep the burner lighted. A shut off valve 5() is also incorporated in the supply line.

Means is provided for affording communication between the lids 7, S, 9, and 10 so that the heat from the one burner serves to heat all the lids. For this purpose the adjacent or confronting portions of adjacent lids are cut away or formed with open- 55 and connections 56 are provided to form closed conduits 'between the openings Except for the openings the periphery of the lids may be solid. rfliese connections 5G may be advantageously constituted of sheet metal plates 57 .extending between adjacent lids and fitted in notches formed in the lids. The plates 57 are held in position by U-shaped cross plates 58, the plates 53 being more properly of inverted U-shaped form and having attaching lug-s fastened to the stove top. A bottom plate 60 having an asbestos [facing 31 is provided on the bottom of each connection 55. The lids 7, 8, and 9 have inte'grally formed therewith bottom plates 62 so that all of the lids have closed bottoms except the one lid to which heat is supplied directly from the burner. The under side of the top of the stove and the bottom plate 62 of the lids may be covered by sheet metal having an asbestos facing.

V1`he lid T is formed with an outlet (S5 for the gases.

rIhe plug 15 is provided with an apertured lug 15 to facilitate handling.

Vdith this arrangement a single burner may be used to effectively heat a plurality of lids so that a number of cooking utensils may be simultaneously heated from a single burner. In this Way the heated gases which are ordinarily wasted are utilized to the fullest extent so that a high economy i-n the use of fuel is effected and efiicient heating action is had. The invention has a further advantage in that the cost 'of providing an in'- dividual burner for each lid is avoided.

The burner structure provided insures the efficient generation of a high' degree of heat and due to the fact that the gases are confined when all of the lids are used until they iave passed out through the outlet 65 odors and fumes are eliminated since complete combustion is had. Of course it is to be understood that when the lids are used cooking` utensils rest on the beveled top walls thereof and close the open tops of the lids to prevent escape of the gases.

As shown in Fig. A5) the burner pipe 14 has a iiller rod 14 provided therein to define a restricted passage 14b for the fuel. In lieu of the fuel -rod 14n the pipe 14 may be filled with wires and the interstices to the wires provide the restricted passage for the fuel. By restricting and retarding the flow lof the fuel through the burner pipe to the amount necessary to proper combustion safety in operation is assured.
